Plugins: a command can ask for its parameters in a dialog (#1547) by elpidioassinaturas · Pull Request #1723 · opengeos/RustGIS

elpidioassinaturas · 2026-11-10T11:21:58Z

Closes #1547.

A plugin command can now declare form, a list of fields like a tool's parameters. Its ribbon button (or tab entry, Command Search entry or shortcut) then opens a dialog with those fields instead of running the command. Run runs the command with their values as its parameters and shows what it answers under the fields. Scripts, rustgis-cli and agents run the command as before, with the parameters they give.

The use cases are in the issue: BrasilData's hotspot period, and the Classificador plugin's six steps, which shared one panel (see the comment with screenshots).

What changes

Manifest (crates/plugins/src/manifest.rs): CommandDecl.form: Vec<ParamDecl>, empty by default and not serialized when empty. Fields are checked like tool parameters: names, kinds, choices, at most 32. The tool checks moved into one check_params, which tools and forms share; the tool error messages are unchanged. FORM_KINDS is the tool kinds plus rasterLayer, without file. check_form refuses the plugin, naming the field, where the dialog would otherwise drop or replace something unseen. That covers a default of another kind than its field (a choice default must be one of its choices), and a field or numericField without a vector layer field above it (vectorLayer, polygonLayer or pointLayer, required when the field is), whose list would stay empty.
Opening (crates/ui-egui/src/lib.rs): run_by_user opens the dialog when a plugin command with a form is asked for without parameters (null or {}, as keymap::Binding::runs treats them). That is how the ribbon, tab entries, panel buttons, Command Search and shortcuts ask for it, so all of them open the dialog, and ribbon.rs is unchanged. ui.pluginForm {"plugin", "command"} opens it directly.
The dialog (crates/ui-egui/src/plugindialog.rs, new): the command's help, then one widget per field. Layers are filtered by kind. A field lists the fields of the nearest layer above it. Numbers are typed, and an optional one left empty is left out; text that isn't a number holds Run, and so does a number a float would round (an integer past i64, or a whole number written as a decimal from 2^53). The manifest reads number defaults with the same plugins::form_number. Text, choices (with translated labels) and checkboxes have their own widgets; an optional checkbox without a default is sent once ticked, and a required one is sent as false until it is ticked. Required fields are marked with *. A required layer starts at the active layer when it is of the kind, otherwise at the first layer of the kind. An optional layer starts at — and can be set back to it. Run stays disabled until the required fields are filled in, and its hover text names them. The answer appears under the fields: the report text when the command answers {"report": "…"}, otherwise the answer as JSON without panel. Errors show in red. The dialog shows the first 64 KB of an answer, then a line saying how many characters more there are: in a UI test a frame took 100 ms with 1 MB shown, 1.9 s with 16 MB, and 11 ms with the cap. Run sends the values of the form as it is then, so a plugin replaced while its dialog is open gets no value for a field it dropped. Each dialog keeps its values for the session, also when another dialog replaces it. A kept value that no longer fits the form (after the plugin changed it) starts over at the field's default, and a field added since starts at its default; a field the user left empty stays empty. The dialog also checks defaults against their fields, as a backstop to the manifest check.
Running (crates/ui-egui/src/pluginstart.rs): Run asks for the command through RustGisApp::ask_plugin, the pluginstart part of run_by_user, so the command starts the same way as a ribbon button ([Bug]: A plugin command that reads a feature service freezes the desktop window with no sign it has started #1319). The window shows it running first, clicks held during a long run are dropped, and the same command with the same parameters is not queued twice. run_next passes the answer to the dialog. The dialog takes only its own run's answer: while that run still waits, an answer of the same command run with other parameters is ignored. When the command waits for the web, the dialog keeps waiting, and run_again passes the answer once the command runs again. If a run ends without an answer, for example because another project opened before it started or its downloads never came, the dialog says it stopped and points to the notices. It never waits forever.
Docs (docs/plugins.md): commands[].form, report, the limits, and what older versions do.

Choices

Run, with the result in the dialog, instead of OK/Cancel (changed from the issue's first proposal). For analysis steps the result is the point: change a value and run again without reopening. The window's × closes the dialog.
report is a plain-text key of the answer. It needs no new host request. Commands that also update a panel keep doing so.
rasterLayer only in forms. A command reads layers itself, by name. Tools still refuse it, because they receive features, not rasters. A test checks both.
No file in forms. A command that wants a file has host calls for it, behind the files permission, so the permission rules stay as they are.
The command is asked for, not run directly. The prototype ran it from the dialog with RustGisApp::run. That bypassed what [Bug]: A plugin command that reads a feature service freezes the desktop window with no sign it has started #1319 added for clicks, so the dialog reuses that path.

Limits

Older RustGIS versions ignore form. Their button runs the command without these parameters. The docs say to set minRustgisVersion, or to make the command answer what it needs in that case.
Not included yet, possible follow-ups: presetting the form from an answer (choice 4 of the issue), fields that show only for some choices, a date kind, and starting a layer field from the value the plugin's other dialogs used.
The values are kept while RustGIS runs. They are not saved with the project. A value that no longer fits (a layer removed or renamed) goes back to the start rule above, and the drop-down shows it.
A field's values come from the layer above it. When that layer is a raster, the field list is empty.
An answer that arrives after the dialog was closed, or replaced by another dialog, isn't shown. Its errors are still notices.
Left for later from the review rounds, each answered in its thread:
- The answer is formatted in full once before the 64 KB cap. That happens once per answer, not each frame, and isn't measured.
- A dialog stays open, with its values, when another project opens. The values stay visible, and layer fields follow the new project's layers.
- Retried answers carry no parameters from the engine. So a retry of the same command with other parameters that finishes in the same poll as the dialog's own retry could be shown.
- A text box sends "" once it has been typed in and emptied, by design.
- Interface strings built with format! are left for the release quality pass.

Size

About 900 added lines: 622 in the new plugindialog.rs (about 190 of them tests), 93 changed in manifest.rs (mostly the existing parameter checks moving into check_params), 28 in the plugin tests, and the rest in lib.rs, pluginstart.rs and the docs. That is more than a small PR should be. I kept it in one PR because the manifest field does nothing without the dialog, and the dialog has nothing to read without the field.

Tests

rustgis-plugins: command_dialog_fields_are_checked. It checks that form fields validate, that a default of another kind than its field (or a choice default outside its choices) is refused, that a field without a vector layer above it is refused, that rasterLayer is accepted in a form and refused in a tool, that file and repeated names are refused, and that a command without form still parses.
rustgis-ui-egui: a_command_dialog_runs_with_its_values_and_shows_the_answer. run_by_user with no parameters opens the dialog instead of running the command. The fields start where the rules above say. Run waits for a required field. It asks for the command and waits for the window before starting. The answer is echoed with the values. An error is shown. Values come back after another dialog. A command without a form has no dialog. optional_fields_left_alone_are_left_out: {} opens the dialog, optional numbers and checkboxes never set are left out, text that isn't a number holds Run, and a typed number is sent. another_runs_answer_is_not_the_dialogs checks that another run's answer isn't taken for the dialog's. kept_values_that_no_longer_fit_start_over checks that kept values that no longer fit are dropped. the_answer_shown_is_its_report checks how answers are shown.
cargo fmt, cargo clippy -D warnings and the tests of rustgis-plugins and rustgis-ui-egui pass locally (Windows).

Screenshot

The test plugin's echo command, with a form, on the World Atlas sample (rendered by the UI test harness). It answers with the request it was sent.

Opened: the required layer starts at the active layer, and the field at its default. The optional raster is left out. Run waits for the required output name.

After Run: the answer is under the fields, and here it shows the parameters the command received.

Summary by CodeRabbit

New Features
- Plugin commands can now open interactive dialogs with fields for layer and field selection, choices, numbers, booleans, and text.
- Dialogs validate required entries and numeric values, retain compatible values when reopened, and display command results or errors.
- Commands with dialogs open them when requested without parameter values.
Documentation
- Plugin documentation now covers command dialogs, supported fields, defaults, validation, compatibility, and parameter limits.

Its ribbon button (or tab entry) then opens a dialog with those fields; Run runs the command with their values as parameters and shows its `report` text, or its answer, under them. The run waits two frames so the dialog shows it running first. Values are kept per dialog for the session. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough

Plugin commands can declare validated forms. The UI opens a dialog for qualifying command requests, submits compatible form values, and displays matching results or errors. Scripts and agent invocation remain unchanged, as documented.

Changes: Plugin command dialogs

Layer / File(s)	Summary
Form declarations and validation `crates/plugins/src/manifest.rs`, `crates/plugins/src/lib.rs`, `crates/plugins/src/tests.rs`, `docs/plugins.md`	Command declarations now accept optional forms. Shared parameter validation checks tool parameters and command forms, with form-specific checks for defaults and layer dependencies. Public exports, tests, and plugin documentation cover the added form support.
Dialog state, controls, and results `crates/ui-egui/src/plugindialog.rs`, `crates/ui-egui/src/lib.rs`	The UI retains compatible form values, renders supported controls, validates required fields and numbers, and displays results or errors. Tests cover submission, retained values, answer matching, and output formatting.
Command launch and answer routing `crates/ui-egui/src/lib.rs`, `crates/ui-egui/src/pluginstart.rs`	Requests with empty parameters open a command form when one is declared. Plugin startup and retry results are routed to the matching dialog. The UI also exposes `ui.pluginForm` and draws the dialog each frame.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Explanation

The manifest validation, dialog controls and state, plugin-start routing, tests, and documentation support the command-form feature in #1547. The answer display, validation, and run-matching behavior support the requested form workflow. No unrelated change is established by the available summary.

Explanation

Docstring coverage is 88.89% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 27 functions across 6 files. (1 skipped: 1 unsupported.)

Full details: Linked Issues check

Explanation

Most coding requirements in #1547 are met. The PR adds validated command forms, opens them for UI requests without parameters, sends form values through the plugin-start path, preserves values during the session, and keeps script and CLI execution parameter-driven. The Run-and-result interaction differs from the proposed OK/Cancel controls but still supports running and closing the dialog. However, #1547 requires a command answer to preset form values. The current PR description lists answer-based presetting as a follow-up, and the change summary describes answer display and value retention but not applying answer-provided form values.

Resolution

Implement answer-based form presetting for command dialogs as required by #1547, and add automated tests that verify returned form values are applied.

+        // A plugin's with a dialog opens it, from the ribbon, Command Search or a shortcut alike
+        // (#1547): its Run gives the parameters.
+        if params.is_null()


Bug (confidence: moderate-low). The dialog opens only when params.is_null(), but keymap::Binding::runs (keymap.rs:193) treats {} as "no parameters" too. A shortcut whose stored params are {} (from preferences or an imported keymap) would skip the dialog and run the command bare, so the same action behaves differently by how the shortcut was stored. Use the same predicate:

Suggested change

if params.is_null()

if (params.is_null() || params.as_object().is_some_and(|o| o.is_empty()))

Fixed in 161cb71. run_by_user now opens the dialog for {} as well as null, the same as keymap::Binding::runs. I didn't take the suggestion alone: with it, a dialog whose fields are all left out would send {} on Run and open itself again. So Run now asks through RustGisApp::ask_plugin, the pluginstart path without the dialog check. optional_fields_left_alone_are_left_out covers both: {} opens the dialog, and its Run with no values runs the command.

+            if r.changed() || !values.contains_key(&f.name) {


Behaviour bug (confidence: medium). !values.contains_key(..) inserts 0 on the first draw of an optional number without a default, and false for a checkbox. The user never set them, and unlike layers and fields there is no way to leave them out, so the command receives trees: 0 even though the form marked it optional. Commands that treat an absent parameter as "use my default" get the wrong value silently.

Suggested direction: only write the value on r.changed(), and show an unset optional number as blank rather than 0. If sending the displayed value is the intent, say so in docs/plugins.md (commands[].form) and add a test with an optional number that has no default.

Fixed in 161cb71. An optional number is now a text field: left empty, it stays out of the parameters. Text that isn't a number holds Run, and the disabled hover names the field. A whole number is still sent as an integer. A checkbox is sent once ticked, or when it has a default; one never set is left out. docs/plugins.md (commands[].form) says so. The new test optional_fields_left_alone_are_left_out runs an optional number and checkbox: nothing set sends {}, 2,5 holds Run, and 2.5 is sent as {"count": 2.5}.

Code review

Bugs

Optional number and checkbox fields with no default are always sent as 0 / false, because the first draw inserts them. The user never set them and cannot leave them out, so commands that treat absence as "use my default" get a wrong value. Confidence: medium. Inline at crates/ui-egui/src/plugindialog.rs:297.
The dialog opens only when params.is_null(), but keymap::Binding::runs treats {} as "no parameters" too. A shortcut stored with {} runs the command bare and skips the dialog. Confidence: moderate-low. Inline at crates/ui-egui/src/lib.rs:2211, with a suggestion.

Security

Nothing found. Plugin labels, help and report text are rendered as plain egui labels, and the new form kinds exclude file.

Performance

Nothing significant. The field and layer lists are rebuilt each frame, but the work is small.

Quality

Nits, left for the release quality pass: the module doc comment in plugindialog.rs (lines 1–5) wraps unevenly, one line in docs/plugins.md (around line 728) is very long, and the lib.rs comment at line 2209 reads awkwardly ("A plugin's with a dialog opens it").
Tests don't cover an optional number without a default, or a {} shortcut.

AGENTS.md

No violations found. Interface strings use tl! and i18n::fmt, the background and cancel rules don't apply to this UI-only change, ui.pluginForm follows the existing ui.* precedent, and the manifest validation is shared with tools.
Prior review threads: none existed, so there were no earlier concerns to skip.

The dialog's Run asks for the command through RustGisApp::ask_plugin, so a form whose fields are all left out runs instead of opening the dialog again. - An optional number is typed, and left out when empty; text that isn't a number holds Run and says which field.

+    }
+    // Fields to fill in before it can run.
+    let missing: Vec<&str> = c


Bug (confidence: medium, low severity). missing and bad are computed before the grid is drawn, but combo fills a required layer or choice during the grid draw. On the first frame after opening, a dialog whose only required field is a layer shows Run disabled with the hover "Fill in: Input", and nothing requests another frame, so it stays that way until the next input event. Computing missing and bad after the grid, inside the same window closure, fixes it. The tests miss this because h.run() runs several steps.

Checked, and it doesn't happen, so no change here. The first frame of an egui window is a sizing pass. It is drawn invisible (Area::show sets .invisible() on the sizing pass, egui/src/containers/area.rs:691), and it asks for another frame (ctx.request_repaint() at area.rs:750-752). combo picks the required layer in that invisible frame, so in the first frame where Run can be seen, missing is already empty. I tested it on this branch: a dialog whose only field is a required layer, stepped until Run shows, has Run enabled in that first visible frame. That test passed without changing the code, so I didn't keep it.

+    let ran = app.session.poll_plugin_retries();
+    for (id, answer) in &ran {
+        crate::plugindialog::answered(app, id, answer);


Bug (confidence: low-medium). run_again passes every retried answer for this command id to answered, and answered only checks the id and whether the command still waits for the dialog's params. A retry for other params of the same command (a shortcut or script with explicit params, while the dialog waits for the web) can therefore become this dialog's result, and clear asked. The retry's params aren't carried in poll_plugin_retries, so matching needs the engine to return them, or the dialog to remember which params it is waiting for and compare.

Fixed in 02ea580. answered now does nothing while the dialog's own run still waits: queued in pluginstart or waiting for the web (pluginstart::waits, which checks both, with the dialog's parameters). Before, it checked only the web wait, so the problem came up in the frames before the run started. In run_next the start is popped before it runs, so its own answer still gets through. Reproduced first by another_runs_answer_is_not_the_dialogs: with the dialog's run queued, an answer of the same command took its place. It is ignored now, and the dialog then shows its own answer. poll_plugin_retries still returns no parameters, so if the dialog's retry and another retry finish in the same poll after the dialog stopped waiting, the dialog can still show the other one. That would need the engine to return the parameters, which I left out of this PR.

+    if let Some(d) = state.open.take() {
+        state.kept.insert((d.plugin, d.command), d.values);
+    }
+    let values = state


Bug (confidence: low). open restores kept values without checking them against the current form. After a plugin reload that changes a field's kind (a number becoming text, say) or drops a field, the stale value is sent on Run: the text widget shows it as empty but does not overwrite it, so the command gets 50 for a text field. Filtering the restored map to the current field names and to kinds that fit would prevent this.

Fixed in 02ea580. open takes kept values only where they still fit the current form: a number for number, a bool for bool, a string for the other kinds. A field that is gone is dropped. A field whose kept value no longer fits starts over at its default, or empty. Reproduced first by kept_values_that_no_longer_fit_start_over: kept {"note": 50, "trees": "many", "gone": 1} came back as they were. Now note (text) is left empty, trees is back at its default 50, and gone is dropped.

Code review

Bugs

plugindialog.rs:115 — missing and bad are computed before the grid draws, so a required layer that combo fills in on the first frame leaves Run disabled until the next input event. Low severity. Confidence: medium.
pluginstart.rs:117 — run_again hands every retried answer for a command id to the dialog, without matching params, so a retry for other params can show up as the dialog's result. Confidence: low-medium.
plugindialog.rs:52 — open restores kept values without checking them against the current form, so a stale value after a plugin reload can reach the command with the wrong type. Confidence: low.

Security

No findings. Dialog Run goes through ask_plugin and the existing prepare_command path, the file kind is refused in forms, and ui.pluginForm only opens a window.

Performance

plugindialog.rs:~187 — a command's report or JSON answer is shown in full, with no size cap and no truncation notice. A very large answer would be laid out every frame. AGENTS requires that any truncation be reported, so a cap should come with a notice. Confidence: low.

Quality (grouped nits; left for the release quality pass under AGENTS)

plugindialog.rs:308 uses d.fields[i] where get() is the repo's preference. The index is range-bounded, so it can't panic.
manifest.rs ParamDecl doc still says "A tool parameter", though it now also describes command forms.
An optional text field that is typed into and then emptied sends "", while a never-typed one is left out. The docs describe only number and checkbox behaviour.
Decimal commas are rejected ("2,5" holds Run). The behaviour is tested and intended, but users in decimal-comma locales may find it surprising.

AGENTS.md

Older RustGIS versions silently ignore form. The PR documents this and suggests minRustgisVersion. This is the existing convention for new manifest fields, so I'm noting it rather than calling it a violation. Confidence: low.
Both earlier review threads (the {} shortcut case and the optional-number value of 0) are fixed in 161cb718, and I did not raise them again. I left 2 earlier concerns alone because they were already answered.

I did not run the test suite. The PR reports fmt, clippy and tests passing locally on Windows. The Bash tool was blocked from running a grep for line numbers, so I used Grep for those lookups.

…nst the form (opengeos#1547) Review round 2: - answered() now waits while the dialog's own run is still queued in pluginstart, not only while it waits for the web, so an answer of the same command run with other parameters (a retry landing) isn't shown as the dialog's. Reproduced by another_runs_answer_is_not_the_dialogs. - open() takes kept values only where they still fit the form: a field gone is dropped, one of another kind starts over at its default. Reproduced by kept_values_that_no_longer_fit_start_over. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Round 2 is in 02ea580: two fixes, each reproduced by a test first. The first-frame Run point is refuted in its thread.

On the uncapped report: I haven't measured it, so I left it as it is. A plugin answer is bounded by the runtime's 128 MiB message limit (MAX_MESSAGE in plugins/src/runtime.rs), and egui caches the text layout between frames, so an answer isn't laid out again each frame. Command answers shown elsewhere (a panel's text, notices) have no cap of their own either. If a cap is wanted, it should come with a notice of what was cut, as the review says. I'd rather add it once a real answer shows the need, with a measurement.

+            .filter_map(|f| {
+                let v = kept.get(&f.name)?;


Bug (confidence: medium, low severity). When kept values exist, let v = kept.get(&f.name)?; skips any field the kept map lacks, so its default is never applied. A plugin update that adds a field with a default (say trees, default 50) gives a blank number box on reopen, and the command gets no trees at all, although a fresh dialog would start at 50. The same happens to any field the user cleared on purpose, so a fix must tell those apart. Either record which field names the kept values were taken from, or store a cleared number explicitly. Falling back to the default for every absent field would bring back a cleared optional number with a default on each reopen. Worth a test with a form that gains a defaulted field.

Fixed in 8f2c2db. When a dialog's values are kept, each field left empty is now stored as null (keep). On reopen, null keeps the field empty: a cleared number stays cleared. A field missing from the kept values was added since, so it starts at its default. Reproduced first by kept_values_that_no_longer_fit_start_over, extended for this case: values kept before trees (default 50) and method (default b) existed now bring both back at their defaults, and other, kept as null, stays empty.

+    }
+    let defaults: Map<String, Value> = c.form.iter().filter_map(|f| f.default.clone().map(|d| (f.name.clone(), d))).collect();


Bug (confidence: medium). Manifest defaults are not checked against the field's kind, and fits is applied only to kept values. A text field with "default": 5 shows an empty box, because the text widget reads only strings, yet values still holds 5 and Run sends it. A bool default of "yes" has the same mismatch: shown unticked, sent as "yes". Applying the same check to defaults closes it. Reading default only as a string or bool is the widget's own rule, so a default of the wrong type should never be sent unseen.

Suggested change

let defaults: Map<String, Value> = c.form.iter().filter_map(|f| f.default.clone().map(|d| (f.name.clone(), d))).collect();

let defaults: Map<String, Value> = c.form.iter().filter_map(|f| f.default.clone().filter(|d| fits(f, d)).map(|d| (f.name.clone(), d))).collect();

Fixed in 8f2c2db, with the suggested line: defaults go through fits too. fits now also accepts a number written as text for a number field, because that field reads text. Reproduced first by optional_fields_left_alone_are_left_out, extended with a text field whose default is 5. Before, Run sent {"label": 5} while the box showed empty. Now it sends {}.

+                            ui.add(egui::Label::new(RichText::new(t).monospace()).selectable(true));


Performance (confidence: medium). The whole report (or the JSON answer) is laid out as a selectable monospace label on every frame, with no size cap. A plugin answer can be large: the wasm runtime accepts messages up to 128 MB, and a process answer up to 256 MB (MAX_QUEUED_BYTES). A multi-megabyte report would make the window slow to draw while it is open. Cap what is drawn, for example at 64 KB, and say how much is hidden under the text (… N more characters not shown), so nothing is cut silently. The full answer is still in the notices or the command's own output, so this only affects the dialog's view.

Fixed in 8f2c2db, after measuring. In the UI test harness on this branch, a frame took 1 ms with no answer, 100 ms with a 1 MB answer, 411 ms with 4 MB and 1.9 s with 16 MB. The dialog now shows the first 64 KB of an answer or error, cut at a character boundary. Under it, a line says … N more characters not shown. With the cap, the 1, 4 and 16 MB answers each draw in about 11 ms. the_answer_shown_is_its_report checks the cut and the count. The docs (commands[].form) say so. This answers the same point from round 2 (issuecomment-6766935429), where I had held off without a measurement.

Code review

I found three new issues, all in crates/ui-egui/src/plugindialog.rs, and posted each as an inline comment. The rest is grouped below. Five earlier threads were left alone (see the end).

Bugs

Fields absent from kept values lose their defaults (plugindialog.rs:60), confidence medium, low severity. After a plugin update adds a defaulted field, reopening the dialog leaves it blank and the command never receives it. The fix must tell this apart from a number the user cleared on purpose.
Manifest defaults are not checked against the field kind (plugindialog.rs:52), confidence medium. A text default of 5 displays empty but is sent as 5. A suggested one-line fix is in the comment.

Performance

Uncapped answer rendering on every frame (plugindialog.rs:208), confidence medium. A large report is laid out in full each frame. A cap with a visible "N more characters" note is suggested.

Security

None found. Plugin text is rendered as plain labels, values reach commands only through the same ask_plugin path as a ribbon click, and the save-prompt replay list does not include plugin commands.

Quality

Decimal comma rejected (plugindialog.rs:291), confidence medium-low. 2,5 holds Run, which is awkward for the Portuguese-speaking users in the BrasilData case. The analysis tools already accept a single decimal comma in cell values (crates/analysis/src/tools.rs:3188). This is a product decision, so I did not post it inline.
Nits, for the release quality pass: d.fields[i] in field() could use get() as the repository asks; long comment lines in the new module doc (plugindialog.rs:281-283) and in the run_by_user doc (lib.rs:223); format! is used for the dialog title and the * marker.

AGENTS.md

Checked: no unwrap/expect/panic in non-test code, no unsafe, no new background command, no ribbon or asset change, and UI strings use tl!/i18n::fmt. Nothing violates the file.
The report-only notices pattern holds: the "stopped without an answer" message points to the notices, and ask_plugin errors go through command_failed.

Already raised, left alone

Five earlier review threads on this PR were not repeated:

plugindialog.rs:135 (first-frame missing): the author showed it does not happen.
pluginstart.rs:117 (retry answers matched only by command id): fixed in part, and the remaining gap is acknowledged by the author.
lib.rs:2211 ({} should open the dialog): fixed in 161cb718.
plugindialog.rs:297 (optional numbers sent as 0): fixed in 161cb718.
plugindialog.rs:52 (kept values not checked against the form): fixed in 02ea580c.

… long answers are cut (opengeos#1547) Review round 3: - Kept values mark each field left empty with null, so a field a newer plugin adds (absent from them) starts at its default, while one the user emptied stays empty. - Defaults go through the same fits() check as kept values: a text field with a number default showed empty and sent the number. - The dialog shows the first 64 KB of an answer and says how many more characters there are.

+
+/// What a command answered, as the dialog shows it: its `report` text, or the answer itself
+/// (without the panel state it may carry).
+fn report(answer: &Value) -> String {


Performance (confidence: medium-low). answered calls shown(report(a)) on the UI thread, and report builds the whole answer before shown caps it. For a report string it clones all of it (t.to_string()). For a JSON answer it clones every value except panel (rest) and pretty-prints the whole thing. The 64 KB cap only limits drawing, so a multi-megabyte answer still costs a full clone and pretty-print in one frame, once per run. The earlier measurement covered only drawing. Cap before formatting: truncate the report text before cloning it, and for JSON write into a size-limited writer (or cap the string before to_string_pretty).

Not changed: I have no measurement for this, and it runs once per answer, not once per frame. Before this point the runtime has already parsed the whole answer from JSON text into a Value, for every plugin command. That parse costs at least as much as the clone and pretty-print here, so a multi-megabyte answer already costs a frame or two of this order whether or not a dialog is open. What I measured and capped in 8f2c2db was the cost that repeated on every frame while the dialog stays open. If an answer that big shows up in practice, capping before formatting is straightforward: cut the report text before cloning it, and use a size-limited writer for JSON.

Quality, never-silent (confidence: medium). A manifest default of the wrong kind is accepted by Manifest and then dropped here by fits: "default": 5 on a text field, or "yes" on a bool, leaves the box empty with no notice and no error at load. Tools have the same gap, because check_params checks only the default's length. AGENTS.md asks that a reader refuse or report what it can't use. Suggest checking each default against its kind in check_params (number takes a number or numeric text, bool a bool, the others a string), so the plugin is refused at load with the field named. Keep this fits filter as a backstop for kept values.

Fixed in 9186f5f. Manifest::parse now refuses a dialog field whose default is of another kind than the field. number takes a number, or a number written as text. bool takes true or false. The other kinds take text. The error names the field: 'save' has a default of another kind than its field (bool). I reproduced it first in command_dialog_fields_are_checked, where "many" on a number, 5 on a field and "yes" on a bool all parsed. The dialog's fits filter stays, as a backstop for kept values. I left tools as they are, because changing what they accept would refuse plugins that load today. That would be a change of its own.

+    // or added since, starts at its default.
+    let values = match state.kept.get(&key) {


Design, inconsistent with pluginstart (confidence: low). The dialog stays open, and its kept values are reused, when another project replaces this one (project.sample, project.open and the rest). pluginstart::drop_replaced drops queued runs for exactly that reason: they "would act on a namesake in the new one". Here combo keeps any same-named layer in the new project, so Run can send the namesake. The value is visible, so this isn't silent, but the dialog should either close or forget its values when session.opened changes, or say so in the docs.

Kept as it is, on purpose. The difference from pluginstart::drop_replaced is what the user sees. A queued run was asked for in the old project, and nothing shows it again before it acts on a namesake in the new one. The dialog shows its values, and Run is a new click on them. Layer fields are checked against the new project's layers on every frame: a layer that isn't there goes back to the start rule (active layer, first layer of the kind, or —), so the dialog never holds a name the new project lacks. If a run is still queued when the project changes, drop_replaced drops it with its notice, and the dialog says the run stopped without an answer. The docs say the values are kept for each dialog until RustGIS closes.

Code review

Bugs

No new bugs found that I'd call confirmed. The dialog's Run calls ask_plugin directly, skipping the save-prompt gate in run_by_user. That is not a new gap: saveprompt::REPLACES covers only core project.* commands, never plugin commands. Confidence: high.
Design inconsistency: the dialog stays open and keeps its values when another project replaces this one, while pluginstart::drop_replaced drops queued runs for the namesake reason. Inline comment posted at crates/ui-egui/src/plugindialog.rs:61. Confidence: low.

Security

None found. The dialog only passes values to the same command path as a ribbon button. The answer is shown as plain text, not markup. The form kinds exclude file. Confidence: medium-high.

Performance

answered → report() clones and pretty-prints the whole answer on the UI thread before shown() caps it. The cap limits drawing only. One-time per run, but a multi-MB answer makes that frame slow. Inline comment posted at crates/ui-egui/src/plugindialog.rs:141. Confidence: medium-low.

Quality

Never-silent gap: a manifest default of the wrong kind ("default": 5 on a text field, "yes" on a bool) passes manifest validation and is silently dropped by fits at crates/ui-egui/src/plugindialog.rs:56. Confidence: medium.
Grouped nits, for the release quality pass:
- Optional text emptied sends "", while an empty optional number is left out. docs/plugins.md says nothing about text.
- A required checkbox with no default counts as missing until ticked, so it can't be sent as false without ticking then unticking.
- Confidence: medium.

AGENTS.md

Crate and layer rules hold: no unwraps in non-test code, no unsafe, egui stays in L6, Id::unique and tl! are used the way the rest of the repo uses them.
ui.pluginForm is a ui.* command that opens a window, the same as the existing ui.pane.plugin. Not a violation.
Confidence: medium-high.

Earlier review threads: 8 concerns already raised, all left alone. Six were fixed in this PR and I checked those fixes against the code. Two were answered and remain open by the author's choice: the missing-before-grid first-frame question (answered with a test), and run_again matching retried answers by command id only (the author acknowledged it is not fixed). I did not re-post either.

…t load (opengeos#1547) Review round 4: a dialog field's default the field can't show ("default": 5 on a text field, "yes" on a checkbox) was dropped unseen by the dialog. The manifest now refuses it, naming the field; a number written as text is still a number. The dialog's own check stays as a backstop for kept values.

+        "choice" => {
+            let options: Vec<(String, String)> = f.choices.iter().map(|c| (c.clone(), m.translate(lang, c).to_string())).collect();
+            combo(ui, id, values, &f.name, &options, f.required || f.default.is_some(), None)


Bug (confidence: medium, low severity). A choice default that isn't one of its choices is silently replaced. open puts the default in values, then combo finds it unknown and, because f.default.is_some() makes the field required, inserts the first option, so Run sends that instead. The PR's own rule is that a default the field can't show is refused at load, and this default is one the field can't show. Refuse it in check_form_defaults (manifest.rs), for example: "choice" => d.as_str().is_some_and(|t| p.choices.iter().any(|c| c == t)), with the error naming the field. A test next to command_dialog_fields_are_checked would cover it.

Fixed in b75f478. The check that refuses a default of another kind (now check_form, which replaces check_form_defaults) also requires a choice default to be one of its choices. The plugin is refused at load: 'method' has a default of another kind than its field (choice). Reproduced first in command_dialog_fields_are_checked: a default of "Maximum likelihood" beside the choices ["Random Forest", "Minimum distance"] used to load.

+            let options: Vec<(String, String)> = layer


Bug (confidence: medium, low severity). A field or numericField with no layer field above it (or only a raster layer above it) gets an empty option list, since layer is None. If it is required, combo removes its value, so Run stays disabled with "Fill in: …" and no way for the user to fix it. For example, a form of just [{"name": "col", "label": "Column", "kind": "field", "required": true}] opens a dialog that can never run. Manifest::parse accepts it. Refuse command forms where a field kind has no layer kind before it (manifest.rs, next to check_params), so the plugin is refused at load and the error names the field. The docs (docs/plugins.md, commands[].form) already say a field lists the nearest layer above it, so this only makes that a rule.

Fixed in b75f478. Until now, the dialog showed an empty drop-down with —, and with required Run stayed disabled ("Fill in: Column") with nothing in the dialog saying why. check_form now refuses at load a field or numericField whose nearest layer field above is missing or is a rasterLayer: 'col' lists the fields of a layer, so it needs a vector layer field above it. Both cases are reproduced first in command_dialog_fields_are_checked. The docs now say that layer field must be a vector one.

Code review

Bugs

Choice default not in its choices is silently replaced (medium, low severity). combo swaps an unknown default for the first option, and a required-looking field then sends that. The PR's own rule says a default the field can't show should be refused at load. Inline comment posted on crates/ui-egui/src/plugindialog.rs:394.
A field with no layer above it makes Run permanently disabled (medium, low severity). Manifest::parse accepts a required field with no layer before it, so the dialog can never run. Inline comment posted on crates/ui-egui/src/plugindialog.rs:361.

Security

Nothing found. Dialog text is rendered as plain text, ui.pluginForm only opens a dialog (Run still needs a click), and the dialog routes through ask_plugin as ribbon buttons do.

Performance

Nothing new. The per-frame report cloning and pretty-printing in answered was raised earlier and the author declined to change it. I left it alone.

Quality

A plain optional text field cleared to "" is sent as "", while an optional number left empty is omitted. The docs don't state this (low confidence, nit).
Older RustGIS versions silently ignore form and run the command with no parameters. The docs cover this through minRustgisVersion, which nothing enforces (low confidence, nit).

AGENTS.md

No violations found. Never-crash holds in non-test code, the new user-visible strings go through tl! or i18n::fmt, the UI-only ui.pluginForm sits in lib.rs, and the layering is intact.
I checked the long_commands_stop_when_cancelled_while_they_run requirement. This PR adds no background command or long tool, so no update to those lists is needed.

Prior review threads

I left 10 earlier concerns alone, because the author answered them with a fix or with reasoning I could not overturn, or because they were already raised. Those are the first-frame Run state, the other-run answer taken by answered, the 64 KB display cap, the UI-thread answer formatting, the keep/null handling, the {} shortcut predicate, the optional-number handling, the stale kept values, the manifest default checks, and the project-replacement namesake concern.

I did not build or run the tests; all findings come from reading the diff and the surrounding source.

Bug (confidence: medium). open checks kept values against the form, but show never does, and the plugin can be replaced while the dialog stays open. plugins::register swaps a same-id plugin in place, so an update installed from the plugin manager gives this dialog the new c.form with the old d.values. A field the new form dropped is still sent on Run, and a value of another kind (a number under a text field) is sent unseen, because the widget shows it as empty and never rewrites it. Neither open's checks nor the tests cover this path.

Suggested fix: keep only the values the current form still takes, every frame, before the grid is drawn:

Suggested change

let Some(c) = m.commands.iter().find(|c| c.id == d.command) else { return };

let Some(c) = m.commands.iter().find(|c| c.id == d.command) else { return };

// The plugin may have been replaced while this dialog is open: keep only the values its form

// still takes, as `open` does, so nothing is sent unseen.

d.values.retain(|k, v| c.form.iter().any(|f| f.name == *k && fits(f, v)));

d.texts.retain(|k, _| c.form.iter().any(|f| f.name == *k && f.kind == "number"));

A test would replace the plugin with a changed form while the dialog is open, then check that Run sends only what the new form takes.

Fixed in 55e39e5. Run now builds its parameters from the form as it is at that moment (form_params): each field's value, if it fits the field's kind. A value for a field the new version dropped isn't sent. A value of a kind that changed isn't sent either; a number field shows such text and holds Run with Not a number. I confirmed it first in the harness: after the plugin was unloaded and loaded again with a form without trees, between two frames, the dialog still held trees: 50. The test that clicks Run after the reload never got an answer in kittest, and I didn't find why in reasonable time. So run_sends_only_values_of_the_form_as_it_is tests form_params directly with a dropped field and a field whose kind changed.

Behaviour (confidence: medium-low). An optional text field that was never typed in is left out of the parameters. Typed and then emptied, it sends "". The PR's rule is that an optional field left empty is left out, as a number's and a layer's are, so an empty text box should not send an empty string. A command that checks whether a parameter is present would see the difference. The docs (commands[].form) also say nothing about text.

// Left empty, an optional field is left out, as a number's and a layer's are.

if s.is_empty() && !f.required {

values.remove(&f.name);

} else {

values.insert(f.name.clone(), json!(s));

}

}

If this is the intent, document it in docs/plugins.md next to the number rule, and add a test with an optional text emptied.

Kept as it is: for a text box, empty text is a value. A command may want "" to clear a label or a filter. A number or a layer has no empty value, so leaving it empty leaves it out. A text box never typed into is still left out, so a command can tell the two apart. The docs now say so (commands[].form: a text box sends what it holds once typed in, empty text too), in 55e39e5.

Bugs

Medium confidence: an open dialog keeps its old values when its plugin is replaced in place. plugins::register swaps a same-id plugin without a frame in between, and show() never re-checks the values against the new form. A field the new form dropped, or a value of another kind, is sent on Run unseen. Posted inline at plugindialog.rs:161 with a suggestion.
Medium-low confidence: an optional text box that was emptied sends "", while one never typed is left out. That contradicts the empty-means-omitted rule for numbers and layers, and the docs don't mention text. Posted inline at plugindialog.rs:411 with a suggestion.

Security

None found. Plugin labels, help and choices are shown as plain text. ui.pluginForm only opens dialogs for enabled plugins, and Run goes through the same ask_plugin path as a ribbon button, so there is no policy bypass.

Performance

None new. The clone-before-cap concern on answered (plugindialog.rs:142) was raised earlier and declined, and I have no new evidence against that answer.

Quality

Low confidence: when an answer has both report and other keys, the dialog shows only report and does not say the other keys are hidden (report(), plugindialog.rs). Summary only.
Nits, for the release quality pass: the window title and the "{text} *" label use format! rather than i18n::fmt, and the module doc's line wrapping is uneven.

AGENTS.md

Nothing blocking. ui.pluginForm follows the ui.dialog precedent, so a ui.* command opening a window is consistent with the repo.
The format! items above are the only AGENTS points I found.

Checked

Manifest validation: check_form, check_params, the FORM_KINDS and PARAM_KINDS split, and the defaults checks.
Dialog state: open, keep, shown (UTF-8 boundary handling) and the layer and field combos.
Integration with pluginstart: run_next, answered, waits, run_again.
Non-test code has no unwrap, expect or panic, and the plugin dialog code uses no std::time.

Earlier threads: 16 threads on this PR were already raised. I re-raised none. Most are fixed in the PR; the cross-retry answer mix-up and the project-replacement design were acknowledged or declined by the author, and I found nothing new on either.

+    Some(if x.fract() == 0.0 && x.abs() < 1e15 { json!(x as i64) } else { json!(x) })


Quality (confidence: medium, low severity). The doc comment says a whole number is sent as an integer, but the 1e15 bound sends whole numbers of 1e15 and up as floats. A command that reads as_i64() then gets None for them. Typed digits beyond 2^53 are also rounded here with no notice. Parsing integer text as i64 first keeps those values exact:

Suggested change

Some(if x.fract() == 0.0 && x.abs() < 1e15 { json!(x as i64) } else { json!(x) })

let t = text.trim();

if let Ok(i) = t.parse::<i64>() {

return Some(json!(i));

}

let x = t.parse::<f64>().ok().filter(|x| x.is_finite())?;

Some(if x.fract() == 0.0 && x.abs() < 9.0e15 { json!(x as i64) } else { json!(x) })

Text beyond i64 range still goes through f64 and is rounded silently. Either refuse it as "Not a number" or give a notice.

Fixed in 6f6fd5a, along the lines you suggested. The rounding was a silent approximation, which "Never silent" covers, so I didn't leave it for the quality pass. number now parses an integer as i64 first, so 9007199254740993 is sent exactly. Before, it went as 9007199254740992.0. An integer past i64 isn't taken: Run shows Not a number for it instead of rounding. Other whole numbers (2.0, 1e3) still go as integers below 2^53, where a float holds each one. The doc comment says all this. Reproduced first in the_answer_shown_is_its_report.

Code review

Reviewed by reading the diff and the surrounding source. I could not build or run the tests here.

Bugs: No new bugs found. I traced the dialog's Run path through pluginstart::ask, the queue dedupe, run_next, run_again, and the "stopped without an answer" check, and found no case that loses or misroutes an answer beyond the one the author already documents. The save prompt is not bypassed: it only covers the fixed REPLACES list, which holds no plugin ids. (High confidence)

Security: None found. Run sends only values of the form's own fields, through the same ask path as a ribbon button. The answer is shown as plain text in an egui label, so there is no markup injection. No new host access is added. (High confidence)

Performance: Nothing new. The per-frame work in the dialog is cheap: geometry_type() is a field read, and input_dataset borrows. The prior thread on the full-answer clone and pretty-print in answered() is still open. I left it alone because the author replied with reasoning and no new evidence. (Medium confidence that it is not a problem in practice)

Quality:

plugindialog.rs:337: number() sends whole numbers of 1e15 and up as floats, although its doc comment promises integers. Digits beyond 2^53 are also rounded silently. Inline comment posted with a suggestion. (Medium confidence, low severity)
When an answer has a report key, the dialog shows only that text and drops the other keys with no note. The docs describe this behaviour, so it is a low-severity point. (Medium confidence)
Nits, for the release quality pass: the window title is built with format! rather than i18n::fmt (it is a title, not a message, so this is minor); several doc-comment lines in plugindialog.rs and run_by_user run past 100 columns; the tests call plugins::unload only at the end, so a panicking assertion leaves a plugin loaded for other tests.

AGENTS.md: No violations found. Checked: no unwrap, expect, panic, or unsafe in non-test code; ui.pluginForm follows the existing ui.pane.plugin pattern; ribbon files are unchanged; user-visible strings use tl! or i18n::fmt; the screenshots are in the PR body and not committed; docs are updated; the new ui.* command opens a window as ui.modelbuilder already does, so "commands never open dialogs" is not broken. Not raised: older RustGIS versions silently ignore form. The docs cover this with minRustgisVersion.

Earlier concerns: There are 18 review threads on this PR. I did not re-raise any of them. Each is either fixed in a later commit, answered by the author, or deliberately kept as the author explained. The one new comment does not repeat any of them.

Bug (confidence: high, low severity). This check accepts any finite number written as text for a number default, but the dialog's number() (plugindialog.rs, added in 6f6fd5a) rejects integer text past i64. For example, "default": "99999999999999999999" loads, then open filters the default out with fits and the box opens empty with no notice. The field is optional, so the command gets no value. That breaks the "refused at load, never dropped unseen" rule this PR adds.

The two rules have drifted apart. The fix is to use one parser for both. Move number() into the plugins crate as a pub fn, call it from here (d.is_number() || d.as_str().is_some_and(|t| number_text(t).is_some())), and have plugindialog.rs call the same function. A test with that default in command_dialog_fields_are_checked would pin it.

Fixed in 89ec7f0, as you suggested: one parser for both sides. form_number is now a pub fn in the plugins crate (re-exported). check_form uses it for a number default, and the dialog's number() only calls it. So the manifest refuses "default": "99999999999999999999" at load, naming the field, and the two rules can't drift apart again. Reproduced first in command_dialog_fields_are_checked: that default used to load.

Code review

Bugs

Number default text that is integer-valued but past i64 (e.g. "99999999999999999999") passes the manifest check. The dialog's number() rejects it, so open silently drops the default and the optional field opens empty. This is a regression from the i64 change in 6f6fd5a. Posted inline at crates/plugins/src/manifest.rs:448 with a fix that shares one parser between the manifest and the dialog. Confidence: high. Severity: low.

Security

None found. The dialog only runs the command through the existing ask_plugin path. ui.pluginForm takes only a plugin and command id.

Performance

None new. The remaining concern is that answered clones and pretty-prints the full answer before the 64 KB cap. That was already raised and answered, and the code is unchanged, so I left it alone.

Quality

None worth a comment now. Two nits are deferred to the release quality pass per AGENTS.md. The first is that the dialog tests do not cover the web-wait path (run_again). The second is that the d.fields[i] index in field() is safe but breaks the "get() over indexing" habit.

AGENTS.md

None found. The change follows the background-path, notice, and command-id rules. ui.pluginForm is a UI-only command in lib.rs, the same as ui.pane.plugin.

Checked and found sound

Retry ids use the same plugin:<plugin>/<item> format as answered and waits.
The state machine for queued, web-waiting, and stopped runs holds up on reading.
shown() cuts at a char boundary.
The manifest does not use deny_unknown_fields, so the docs' claim that older versions ignore form is correct.

Prior reviews: 19 earlier threads are on this PR. I left all 19 alone and did not re-raise any of them.

+        .filter(|f| f.required && d.values.get(&f.name).is_none_or(|v| v.is_null() || v.as_str() == Some("")))


Bug (confidence: medium, low severity). The Run gate treats a value as filled in whenever it is not null or "". It never checks the value against the field's kind, but form_params does. If a plugin is replaced while its dialog is open, the value can have the wrong kind. Example: a required text field that held a number, after an update makes it text. The text box shows empty, missing stays empty, so Run is enabled. form_params then drops the value, and the command runs without a required parameter. Commit 55e39e5 fixed what is sent, but this gate still disagrees with it.

Suggested fix: use the same rule as form_params, so a value that does not fit counts as missing.

Suggested change

.filter(|f| f.required && d.values.get(&f.name).is_none_or(|v| v.is_null() || v.as_str() == Some("")))

.filter(|f| f.required && d.values.get(&f.name).is_none_or(|v| !fits(f, v) || v.as_str() == Some("")))

A test with a required text field whose stored value is a number would pin it.

Fixed in 38d8629. Run's gate now uses unfilled, which has the same rule as form_params. A required field counts as filled only when it holds a value of its kind (fits) that isn't empty text. A value that form_params would leave out now holds Run, so the command can't run without a required parameter. Confirmed in the code: the gate checked only for a value. run_sends_only_values_of_the_form_as_it_is now also tests unfilled, with a required number holding "b" and holding 3.

Quality / design (confidence: medium-low). Scripts, the CLI and agents see a command's params text (crates/engine/src/cmd/project.rs:655-657 sends c.decl.params as the command's params), and that text defaults to "{}". A command with a form therefore advertises no parameters, so an agent that calls it bare runs it without the fields. The docs (docs/plugins.md, commands[].form) also don't say that params should describe the form.

Suggested fix: say in the docs that a command with a form should also set params to describe its fields for scripts and agents. Deriving the text from form in the engine would be a larger change, which can be a follow-up.

Done in 38d8629, in the docs: commands[].form now says that scripts and agents run the command with the parameters they give, so commands[].params should describe the form's parameters too. I didn't generate params from the form. It is the plugin author's text for people and agents, and it may say more than the form shows (units, what each choice does).

Code review

I read the full diff, the 20 earlier review threads, and the surrounding code: the plugin start queue, the retry poll, the save prompt, and the ui.* dispatch. Two new findings are posted inline. I left all 20 earlier concerns alone. Sixteen are fixed in the code, and four were answered with reasons (first-frame Run gate, clone before the 64 KB cap, dialog kept across project changes, empty text box).

Bugs

Run gate ignores value kind (crates/ui-egui/src/plugindialog.rs:182, confidence: medium, low severity). After a plugin is replaced with a changed field kind, a required field can hold a value of the wrong kind. Run is then enabled, and form_params drops the value, so the command runs without a required parameter. The suggested fix uses the same fits rule as form_params.

Quality

Form fields invisible to agents and scripts (crates/plugins/src/manifest.rs:181, confidence: medium-low). The command's params text, which scripts and agents read, defaults to "{}". Nothing in the docs says to set it for a form command.
Nit, left for the release quality pass: format! is used for user-visible text ("{text} *" and the dialog title) instead of i18n::fmt. The PR already lists this as deferred.

Security

None found. Manifest form fields are bounded, and the new code has no unwrap in non-test paths.

Performance

Nothing new. The per-frame lookups are cheap: plugins::get returns an Arc, and input_dataset returns a reference. The formatting cost before the cap is the earlier thread, which the author declined.

AGENTS.md

The rules I checked are met: no unsafe code, no unwrap outside tests, the layering holds, and the code stays wasm-compatible. The too_many_arguments lint is allowed workspace-wide.

Bug (low severity, confidence medium-high). d.is_number() accepts any JSON number, including integers above i64::MAX that serde_json parses as u64 (e.g. "default": 9223372036854775808). form_number rejects those (its doc: "an integer past i64... isn't taken"), so the plugin loads, then the dialog's number() reads the shown text as not a number. The box holds Run with "Not a number" (or an optional field is left out), which breaks the "refused at load" rule this PR adds. fits in plugindialog.rs:147 has the same v.is_number() gap.

Suggested fix: use one rule for both sides, applied to the JSON number's own text:

Suggested change

"number" => d.is_number() || d.as_str().is_some_and(|t| form_number(t).is_some()),

"number" => match d.as_str() {

Add "default": 9223372036854775808 to command_dialog_fields_are_checked next to the "99999999999999999999" case.

Fixed in 0c3a587. form_number_value (in plugins, re-exported) reads a JSON value with the same form_number rule, whether it is a number or text. The manifest's number default check and the dialog's fits both call it, so "default": 18446744073709551615 is refused at load, naming the field.

Bug (low severity, confidence medium-high). Integer text is said to be exact, but decimal-written integers past 2^53 are rounded silently. For example 9007199254740993.0 misses the i64 branch, parses as f64 to 9007199254740992.0, and fails the < 2^53 test, so the command receives the float 9007199254740992.0. That is the approximation "Never silent" forbids, and the same kind the PR fixed for plain integers.

Suggested fix: refuse integral values at or past 2^53 that didn't parse as i64, so they show as "Not a number" (and are refused at load for defaults):

Suggested change

return None;

}

Some(if x.fract() == 0.0 { serde_json::json!(x as i64) } else { serde_json::json!(x) })

Add "9007199254740993.0" to the_answer_shown_is_its_report's number checks. This also means 1e16 is refused, which is acceptable; say so in the doc comment.

Fixed in 0c3a587, with your suggestion: a whole number written as a decimal or with an exponent, from 2^53 up (9007199254740993.0, 1e16), is no longer taken. Run shows Not a number for it, and a default like that is refused at load. Integers written as integers stay exact up to i64. Decimals with a fraction (0.1) are still read as f64, which every decimal number is subject to, so that isn't a cut this PR adds. The doc comment says so. Reproduced first in the_answer_shown_is_its_report (9007199254740993.0) and command_dialog_fields_are_checked. This rule now covers all three numeric cases: JSON integer, integer text, and decimal-written integer.

Code review

Bugs

Low, medium-high confidence. A number default that is a JSON integer above i64::MAX passes the manifest check (d.is_number(), manifest.rs:464). The dialog then rejects it: the box shows "Not a number" and holds Run, or an optional field is left out. This breaks the refuse-at-load rule the PR adds. fits in plugindialog.rs:147 has the same gap. Inline comment posted with a suggested fix.
Low, medium-high confidence. form_number rounds decimal-written integers past 2^53 without a notice. For example 9007199254740993.0 reaches the command as 9007199254740992.0 (manifest.rs:450). That is the silent approximation AGENTS.md forbids, and the doc comment says integer text is exact. Inline comment posted with a suggested fix.

Security

Nothing found. Plugin-supplied label, help and report are shown as plain egui text, and the dialog opens only for enabled plugin commands.

Performance

Nothing new. The earlier concern about formatting a large answer on the UI thread is already raised and answered, so I left it alone.

Quality

Not posted inline: the choice default message in check_form says "another kind than its field", but the actual rule is "not one of its choices". Wording only.

AGENTS.md

Low confidence: the dialog title in plugindialog.rs show() uses format!, where AGENTS.md asks for i18n::fmt. The author deferred this to the release quality pass, so this is a flag, not a blocker.

Earlier threads: 22 review threads already exist on this PR. I re-raised none of them. The one still open (a retried answer for other parameters can be shown in the same poll) is the author's acknowledged limitation, and no new evidence changes it.

What I checked: the full diff; all 22 prior threads against the current code; pluginstart.rs; the ribbon, panel, Command Search and shortcut call paths into run_by_user; input_dataset (a reference, not a clone, so no per-frame copy); plugins::command; too_many_arguments is allowed workspace-wide, so field() is fine. I did not build or run the tests in this environment, so compile and test status is unverified.

…geos#1547) Review round 12, closing the numeric edge cases under one rule: - A number default given as a JSON integer past i64 passed is_number(); form_number_value now reads JSON numbers and text alike, for the manifest check and the dialog's fits(). - A whole number written as a decimal or exponent from 2^53 (9007199254740993.0, 1e16) was rounded unseen; it is now refused as not a number (and at load as a default). Integers written as integers stay exact up to i64. Reproduced first in command_dialog_fields_are_checked and the_answer_shown_is_its_report. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

+    match answer {
+        Value::Null => tl!("Done.").to_string(),
+        Value::Object(o) => {
+            let rest: Map<String, Value> = o.iter().filter(|(k, _)| *k != "panel").map(|(k, v)| (k.clone(), v.clone())).collect();


Quality, never-silent (confidence: medium-low, low severity). For a JSON answer without report, this filter removes the panel key and the dialog shows the rest with no line saying so. The docs (docs/plugins.md, commands[].form) say "the answer itself, up to its first 64 KB", which doesn't mention the drop either. The panel state does appear in the plugin's panel, so nothing is lost for good, but a reader of the dialog can't tell it was removed.

Either say it in the docs next to the 64 KB sentence, for example "without its panel state, which the plugin's panel shows", or add the same kind of line the 64 KB cap uses when panel is present.

Kept as it is: nothing is lost here. The engine applies panel before the dialog sees the answer (crates/engine/src/cmd/plugins.rs, the answer.get("panel") → state.apply path in plugin command runs). The panel shows it, and anything it can't apply already gets a warning there. The dialog leaves it out because it is panel state rather than a result, and the panel already shows it. Showing it again under the fields would only repeat it as raw JSON.

Follow-up in 4b883db: the docs (commands[].form) now say the answer is shown without its panel state, which the plugin's panel takes in.

Code review

Bugs

No new bugs found. The paths I traced all hold: dialog Run goes through pluginstart, answers route to the dialog only for its own run, kept values are reconciled on open, and form_number rejects text it would round. Cross-file APIs (CmdResult, poll_plugin_retries, PluginCommand, run_prepared) match their uses. Confidence: high.

Security

No issues found. ui.pluginForm only opens a dialog; nothing runs without a click, and Run goes through the same ask_plugin path as a ribbon button. Plugin labels and report text render as plain egui text. Confidence: high.

Performance

No new findings. The per-frame work in show is a few small loops over the form, and the field lists borrow the dataset. The earlier concern about report() cloning and pretty-printing before the 64 KB cap still stands. I left it alone because it is already raised and the author declined it with a reason. Confidence: medium.

Quality

plugindialog.rs:162: JSON answers drop the panel key without saying so, and the docs don't mention it. Low severity. Posted inline. Confidence: medium-low.
Nits, for the release quality pass: the module doc comment (plugindialog.rs header) wraps unevenly, and the run_by_user doc comment in lib.rs has a line past 100 columns. Confidence: high, low impact.

AGENTS.md

Translatable text uses tl! and i18n::fmt. The remaining format! strings are a title and a * marker, which the PR already defers. Background work uses the existing pluginstart path, and too_many_arguments is allowed workspace-wide. No wasm or layering problems. Confidence: high.

Prior reviews: 17 threads were already on this PR. Each one the author answered with a fix or a reasoned decline. I left all of them alone except the report() cap, which I did not re-raise. Nothing in the code they point at has changed in a way that reopens them.

+                let button = ui.add_enabled(!running && ready, egui::Button::new(RichText::new(tl!("Run")).strong()));
+                let button = if !missing.is_empty() {
+                    button.on_disabled_hover_text(crate::i18n::fmt("Fill in: {fields}", &[("fields", &missing.join(", "))]))
+                } else if !bad.is_empty() {


Behaviour, low severity (confidence: high). A required number field holding text that isn't a number (say 2,5) has its value removed by field(), so unfilled puts it in missing. The hover then reads Fill in: Trees while the box shows 2,5, and the Not a number branch below never runs for it. The optional case is handled (bad is shown when missing is empty), and optional_fields_left_alone_are_left_out covers only optional numbers.

Suggested fix: name the fields with bad text in their own message, so the user sees why Run is held. For example, keep missing for empty fields and show Not a number: … for bad as well, or list both in the hover. A test with a required number holding 2,5 would pin it.

Fixed in 4b883db. held now names a required number holding text that isn't a number under Not a number, not under Fill in. Run's hover lists each reason on its own line, so both show when both apply. Tested in run_sends_only_values_of_the_form_as_it_is with a required number holding 2,5.

+        return None;
+    }
+    let x = t.parse::<f64>().ok().filter(|x| x.is_finite())?;


Never-silent gap, low severity (confidence: medium-high). Rust's f64 parse returns Ok(0.0) for a value too small to represent, so 1e-400 (or -1e-400) gets through this line as 0.0, passes the whole-number test, and is sent as the integer 0. The user typed a non-zero value and nothing says it was changed. The doc comment says decimals are read as f64, but it does not cover a value that underflows to zero and then becomes a different whole number.

Suggested fix: refuse a result that is exactly zero while the text has a non-zero digit, for example by checking the parsed value before the whole-number branch. Add "1e-400" to the_answer_shown_is_its_report's number checks.

Fixed in 4b883db. form_number refuses a value that parses to 0.0 when its digits before the exponent include a non-zero one (1e-400, -1e-400). 0e10 is still 0. The doc comment lists it, and the_answer_shown_is_its_report checks both.

Code review

Bugs

Required number field holding non-numeric text (e.g. 2,5): the hover says "Fill in: Trees" instead of "Not a number", because field() clears the value and unfilled lists it as missing. Low severity. Confidence: high. Inline comment posted at crates/ui-egui/src/plugindialog.rs:234.

Security

None found. Dialog text is shown as plain text, and the Run path goes through the same pluginstart route as ribbon clicks. saveprompt is not consulted for plugin commands, but it wasn't before this PR either.

Performance

Nothing new beyond the earlier threads. report() still clones the whole answer on the UI thread once per answer. That thread was answered and I left it alone.

Quality

Nit, grouped: field() indexes d.fields[i] at plugindialog.rs:374. The index is in range by construction, but the repo guideline is get() over indexing.

Never-silent (new)

form_number at crates/plugins/src/manifest.rs:450: 1e-400 parses to 0.0 and is sent as the integer 0 with no notice. Low severity. Confidence: medium-high. Inline comment posted.

AGENTS.md

No new violations found. Layering holds (plugins stays below ui-egui), there are no unwrap/expect/panic calls in non-test code, and the three new tl! strings are wrapped. The format! calls for the window title and the required-field * are not translatable messages, so I did not flag them.

Checked and left alone

25 earlier review threads are already on this PR. The author replied to every one, so I did not repost any. I looked at run_again, answered and waits again: the open point that a retry with other parameters can reach the dialog is one the author acknowledged, so I left it alone.

Other things I checked and found sound

Dialog start-up path (run_by_user → open, and {}/null handling).
run_next and answered ordering.
check_form against the dialog's layer tracking.
Number parsing for integers, exponents and i64 bounds.
Report truncation (shown).
Test expectations for the 64 KB cap and the char boundary.

… underflow to 0 (opengeos#1547) Review round on the ready PR (CodeRabbit and the Claude review): - The dialog showed a command's error as it came, while its notice is redacted: an address's token could show there. error_shown redacts it with Session::redacted, as landed_in_dialog does. - A required number holding text that isn't a number was named under "Fill in"; held() names it under "Not a number", each reason on its own line. - form_number refuses a number other than zero too small for a float (1e-400), which f64 parsing reads as 0. - Docs: the answer is shown without its panel state, which the panel takes in.

+/// What a command answered, as the dialog shows it: its `report` text, or the answer itself
+/// (without the panel state it may carry).
+fn report(answer: &Value) -> String {
+    if let Some(t) = answer.get("report").and_then(Value::as_str) {


Never silent, low severity (confidence: medium-low). When an answer has a report string, report() returns only that text. Every other key of the answer is dropped from the dialog, and no line says so. The 64 KB cap does say how much it hides, and the panel drop is documented, but this one isn't. The docs describe the report text as what the dialog shows, so this is a design choice. It is still data the user can't see, and the fix is small.

Suggested direction: when the answer is an object with keys other than report and panel, add a line after the report such as … N more answer keys not shown (or show the rest as JSON under it). Add a case to the_answer_shown_is_its_report for {"report": "x", "rows": 3}.

Kept as it is, on purpose. report is the text the plugin chose to show the user in the dialog. The other keys of the answer are for whatever else reads it: scripts, agents and the command's callers. The dialog doesn't hide anything from them, because they get the whole answer. docs/plugins.md (commands[].form) says it: "The dialog shows what the command answers: its report text when it answers {"report": "…"}, or else the answer itself". A plugin that wants the user to see a value puts it in the report text. Adding a line about keys left out would show a raw count in the middle of the text the plugin wrote for the user.

Code review

Most of this PR's concerns were already raised in the 28 existing review threads, and the author addressed them. I left all 28 alone and checked the current code for regressions. The one new concern is below as an inline comment.

Bugs

None new. I checked the run-gating, kept-value and answer-matching paths (answered, waits, run_next, run_again), the numeric parser (form_number), and the check_form rules. The dialog's Run skips saveprompt::asks, but that check only matches a fixed list of project-replacing command ids, so it never applies to plugin commands. The residual "another retry in the same poll" case in answered is already raised and left as the author described.

Security

None found. The dialog shows errors through Session::redacted, and no new file, network or permission path is added.

Performance

None new. The per-frame work is O(form fields + layers), and geometry_type() is O(1). The report() clone and pretty-print before the 64 KB cap is already raised and declined (confidence: medium).

Quality

Never silent, low (confidence: medium-low). When an answer has a report string, the dialog shows only that text and drops every other key without saying so. The docs describe this, but the 64 KB cap does announce what it hides. Posted inline on crates/ui-egui/src/plugindialog.rs:177.

AGENTS.md

No violations found. ui.pluginForm follows the ui.pane.plugin dispatch pattern. FORM_KINDS matches the docs. The UI strings use tl! and i18n::fmt. The remaining format! titles are the ones the author deferred to the release quality pass.

I posted 1 inline comment. The other 28 earlier concerns are left alone because they were already raised.
